12 Cool Windows 8.1 Apps

BallStrike

Publisher: GPS Tuner Kit
Though health and fitness-related, this is among the coolest Windows 8.1 apps around. BallStrike uses your webcam in a sort of augmented reality setup in which you hit balls on the screen. It's almost like having a Kinect without having to buy one: The camera tracks your motion, and a "heat map" style image of you shows up on your screen as you swat at the on-screen balls. Not only will this impress you with the technology used, but may even help shed away some extra pounds.
